| 550241 | Action | Biased credit assignment in motivational learning biases arises through prefrontal influences on striatal learning | Go actions (irrespective of left vs. right) compared to baseline at the time of response. This is GLM2. The GLM contains the following 13 regressors: 1-8) 8 regressors crossing the performed action (Go/ NoGo) with the obtained outcome (reward/ no reward = neutral/ no punishment = neutral/ punishment). At the time of outcomes. 9) Left hand response. At the time of responses. 10) Right hand response. At the time of responses. 11) Incorrect response. At the time of responses. 12) Outcome Onset (any outcome). At the time of outcomes. 13) Invalid outcomes (non-instructed key pressed, returning error message). At the time of outcomes. This contrast is based on the left hand response and the right hand response regressors (at the time of responses), taking the sum of both. |
| 550207 | Action | Striatal BOLD and midfrontal theta power express motivation for action | Go trials (Go action performed, irrespective of left vs. right) minus NoGo trials (no action performed). Contrasted at the time people see the cue that requires the action (deadline 1.3 seconds). Too late response are registered as NoGos. Motivational Go/NoGo task (Swart et al., 2017; 2018; van Nuland et al., 2020). Note that this Go/NoGo task is equiprobable (percent Go/NoGo trials is 50:50) and thus does NOT elicit strong inhibition-related activation. |
